Title: Rename free-programming-books.md to free-programming-books-en.md

Per issue #1181, naming convention of collections in other languages is not followed by the English version. Additionally, screencasts and interactive-tutorials already follows the "-en.md" convention, so this brings the file in line with other existing English collections.
